A New Pseudomasaris from California 
67 
(lateral angles and ventral areas) of propodeum; broad 
apical bands on all tergites, those on the first to fourth very 
wide on the sides and abruptly narrowed, the median an- 
terior margin wavy; all the sternites (except for the bases 
and the apical depressed area of the process of the third 
sternite) ; and most of the legs (front coxae, trochanters 
and femora partly black above; middle and hind coxae and 
trochanters black beneath; under side of middle and hind 
femora with a narrow black line; tarsi partly ferruginous) . 
On the fifth abdominal tergite the yellow is very extensive 
and partly divided in the middle by a sharp projection from 
the black base, while there is a free, ovate, black spot on 
each side in the yellow ; the yellow band of the sixth tergite 
is similar to that of the fifth, but there are no free black 
spots ; the four tubercles of the seventh tergite are black and 
the two of each side are connected by a narrow black line. 
Antenna ferruginous to black; scape with a yellow apical 
band; third segment extensively yellow above; the fourth 
to sixth with some yellow streaks on the upper side ; the club 
spotted with yellow at the base both above and beneath. 
Wings subhyaline, very slightly suffused with ferruginous 
brown in the costal, radial and first cubital cells and along 
some of the veins; the veins reddish brown, the stigma 
bright fulvous. The variations of the color in the males are 
slight: sometimes the frontal spots are much reduced or 
even lacking ; the anterior margin of the postscutellum may 
be yellow in the middle ; or the concavity of the propodeum 
may show two or three small yellow spots ; the apical fasciae 
of the first four tergites instead of being wavy, may be more 
angularly emarginate anteriorly. 
Female. — Agrees in most respects with the male, except 
as indicated below. Occipital margin almost straight. Eyes 
not bulging. Inner orbits distinctly, though very little far- 
ther apart at the clypeus than on the vertex. Frons entirely 
flat, without even a trace of median tubercle. Ocular sinus 
broader. Ocelli subequal, in a flattened triangle ; the posteri- 
or ocelli a little closer to each other than to the eyes. Vertex 
flat, not sloping, without fovea. Antennae about five times 
as far apart as they are from the inner orbits. Clypeus
